3D Aluminum Letters – Carved & Backlit

DIKA SIGN 3D carved and backlit aluminum letters combine a sculpted aluminum face, rear-mounted LED lighting and a custom recessed installation structure. They can be integrated with marble and other architectural finishes.
By day, precision-shaped bevels and grooves create distinctive metallic depth. When illuminated, soft contour lighting accentuates the letterform while supporting nighttime visibility.
Designed for luxury residential building numbers, commercial building entrances, parking-garage access points, and hotel or office identification, each project can be customized in size, finish, lighting and mounting structure.

Typical Applications
✓ Luxury residential building entrances
✓ Retail and commercial unit entrances
✓ Parking-garage building entrances
✓ Hotel and office building identification

Key Advantages

3D-Carved Detail, Refined Appearance

Beveled surfaces, recessed grooves and defined edges give aluminum building numbers a layered metallic appearance.

Soft LED Backlighting, Clearer Contours

LED placement and light paths are engineered around the letterform to balance visibility with the surrounding architectural ambience.

Recessed Stone Integration, Precise Installation

Stone cutouts, fixing details and cable routing are coordinated during engineering to reduce on-site fitting issues.

Project Challenges & DIKA SIGN Solutions

3D Aluminum Letters – Carved & Backlit 11

Product Challenge 01>>

Flat Building Numbers Lack the Depth Expected in Premium Spaces

Luxury residences and commercial properties often feature marble, metal and other premium finishes. Flat building numbers can appear visually weak against these materials.

Limited dimensional detail in daylight

Poor proportions between lettering, stone and wall finishes

Differences between renderings and finished samples

>> DIKA SIGN ® Solution

Refine bevels, grooves and relief profiles in the 3D

carved aluminum design

Coordinate metal finishes, surface textures and

mounting proportions with the architecture

Verify carved details and finishing with a physical

sampleunlit states on a physical sample

>> Solution Value

A cohesive visual identity between dimensional
aluminum building numbers and the surrounding
stonework.

Product Challenge 02>>

Uneven Backlighting Reduces Nighttime Clarity

Stroke widths, corners and recess depths vary across 3D carved letters. Poor LED placement or light-path design can create hotspots, gaps or glare.

Discontinuous lighting around narrow strokes or curves

Visible LED points

Differences between expected and installed lighting effects

>> DIKA SIGN ® Solution

Optimize LED placement, recess depth and illuminated

gaps

Select light sources, color temperature and electrical

components for the project

Review illuminated and unlit states on a physical sample

>> Solution Value

Soft contour lighting that emphasizes 3D detailing and

improves nighttime visibility with less on-site adjustment.

Product Challenge 03>>

Stone Integration and Outdoor Protection Create Installation Risks

Illuminated building numbers must fit precisely within marble or other cladding. Outdoor entrances and parking-garage areas also require attention to moisture exposure, electrical protection and maintenance access.

Mismatch between aluminum letters and stone cutouts

Insufficient fixing, wiring or maintenance space

Increased electrical risk from water or damp

>> DIKA SIGN ® Solution

Check stone openings, recess depth, fixings and cable

exits before production

Specify finishes and electrical protection for indoor, semi-

outdoor or exposed conditions

Coordinate sealing, drainage, access and installation

details

>> Solution Value

Cleaner, more reliable recessed installation with fewer

on-site corrections and reduced maintenance risk.

Frequently Asked Questions

How are 3D carved backlit aluminum letters different from standard illuminated letters?

They feature a sculpted aluminum face with bevels and recessed details. LEDs positioned within the rear recess create contour lighting that complements the dimensional metalwork, rather than relying mainly on a front-illuminated face.

Can these letters be installed outdoors or at parking-garage entrances?

Yes, subject to project-specific finishes, electrical protection and mounting details. Any required outdoor or damp-location rating must be confirmed against the final configuration and testing.

Can the letterforms, metal finishes and LED color temperatures be customized?

Yes. Numerals, letters, bevel profiles, finishes, light colors and mounting structures can be developed from drawings and confirmed with a pre-production sample.

Do you make large building numbers or complete building-number sets?

Yes. Feasibility, segmentation and mounting are assessed against letter size, stroke geometry and substrate. Oversized designs should be reviewed for structural, shipping, lifting and maintenance needs.

Can North American projects use a UL 48-compliant electrical configuration?

DIKA SIGN can assess applicable UL 48 certification requirements for North American projects. UL-recognized components alone do not certify the complete sign; labeling and certification depend on the final product configuration and supporting documentation.

What engineering, manufacturing and installation support does DIKA SIGN offer?

We provide drawing review, shop drawings, samples, custom manufacturing and quality control. Installation services are available for domestic projects in China. For overseas OEM/ODM partners, we provide manufacturing and technical support; on-site installation is excluded.
